During World War I, submarines emerged as a pivotal technological advancement, fundamentally altering naval warfare. These underwater vessels revolutionized military strategies by disrupting enemy supply lines and naval operations, showcasing the power of stealth and surprise beneath the ocean’s surface. The introduction of submarines not only challenged traditional naval tactics but also highlighted the importance of innovation in modern warfare. In the realm of chemistry, 1915 witnessed a different kind of innovation with Thomas Lyle Williams’ introduction of Maybelline mascara. This cosmetic breakthrough marked a significant development in cosmetic chemistry, transforming the beauty industry and offering new possibilities for enhancing one’s appearance. The creation of Maybelline reflected a fusion of science and aesthetics, demonstrating how chemistry could revolutionize personal care and self-expression. Furthermore, the establishment of the National Advisory Committee for Aeronautics (NACA) in March laid the foundation for advancements in aeronautics and space exploration. This precursor to NASA paved the way for groundbreaking discoveries in aviation and aerospace technology, shaping the future of human exploration beyond Earth’s boundaries. Additionally, Georges Claude’s patent of the neon discharge tube for advertising signage in January showcased the intersection of science and commercial applications, illuminating cities with vibrant neon lights and revolutionizing visual communication in urban landscapes. These developments in submarines, chemistry, aeronautics, and lighting underscored a period of diverse scientific and technological progress that left a lasting impact on society and warfare.
